Paper-box handle structure

ABSTRACT

A paper-box handle structure includes a folding region having an opening and a handling region integrally formed with the folding region. The handling region comprises a cantilevered part passing through the opening of the folding region to form a handle.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a paper-box handle structure, and moreparticularly to an integrally formed paper-box handle structure.

2. Description of the Related Art

In FIG. 1, a conventional handle structure 10 comprises a handlingelement 1 and a fixed element 2. The handling element 1 comprises aholding portion 11 and two rectangular positioning portions 12 formed attwo ends of the holding portion 11, respectively. The fixed element 2comprises two rectangular openings 21 corresponding to the positioningportions 12 of the handling element 1. The long side length of thepositioning portion 12 is greater than the short side length of theopenings 21 of the fixed element 2.

In FIG. 2, a plate b20 of a paper box B is provided with two holes (notshown in Figs.) corresponding to the rectangular openings 21 of thefixed element 2. The handling element 1 and the fixed element 2 of thehandle structure 10 are installed on the paper box B by insertingrectangular openings 21 of fixed element 2 by into corresponding holesin the bottom of plate b20 of paper box B. The positioning portions 12of the handling element 1 are plugged sequentially into the holes of theplate b20 of the paper box B and the rectangular openings 21 of thefixed element 2. When the positioning portions 12 of the handlingelement 1 fully pass through the holes of the plate b20 of the paper boxB and the rectangular openings 21 of the fixed element 2, the long sideof the positioning portions 12 of the handling element 1 aresubstantially perpendicular to the long sides of the rectangularopenings 21 of the fixed element 2, thus, the handling element 1 issecurely engaged to the plate b20 of the paper box B. By holding theholding portion 11 of the handling element 1, the paper box B can beeasily moved.

The handling element 1 and the fixed element 2 are two individualelements, thus, reducing material costs and assembly time is difficult.Precision and tolerance of the handling element 1 and the fixed element2 must also be considered.

BRIEF SUMMARY OF THE INVENTION

An integrally formed, single source material paper-box handle structurecapable of being rapidly assembled is provided. An exemplary embodimentof a paper-box handle structure comprises a folding region having anopening and a handling region integrally formed with the folding region.The handling region comprises a cantilevered part passing through theopening of the folding region to form a handle. The paper-box handstructure further comprises a folding line next to the folding region.

The handling region further comprises a first body. The cantileveredpart comprises a fixed end securely connected to the first body and afree end formed with an engaging portion, thus, the free end formed withthe engaging portion is engaged in the opening of the folding region.

The opening of the folding region comprises a first width and theengaging portion of the free end comprises a second width greater thanthe first width, thus, the engagement of the free end of thecantilevered part is limited by the opening of the folding region whenthe free end of the cantilevered part passes through the opening of thefolding region.

The paper-box handle structure can comprise plastic.

A detailed description is given in the following embodiments withreference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention can be more fully understood by reading the subsequentdetailed description and examples with references made to theaccompanying drawings, wherein:

FIG. 1 is a schematic view of a conventional handle structure;

FIG. 2 is a schematic view of the conventional handle structure disposedon a plate of a paper box;

FIG. 3 is a schematic view of a paper-box handle structure of theinvention; and

FIG. 4 is a schematic view of the paper-box handle structure disposed ona plate of a paper box.

DETAILED DESCRIPTION OF THE INVENTION

The following description is of the best-contemplated mode of carryingout the invention. This description is made for the purpose ofillustrating the general principles of the invention and should not betaken in a limiting sense. The scope of the invention is best determinedby reference to the appended claims.

In FIG. 3, a paper-box hand structure 100 comprises a handling region30, a folding region 40 and a folding line 50 disposed next to thefolding region 40. The folding region 40 comprises a longitudinalopening 41 formed along the X direction of an X-Y coordinate system. Thehandling region 30, integrally formed with folding region 40, comprisesa first body 300 and a cantilevered part 30 c cut from the first body300 along a trim line 301. The cantilevered part 30 c is centrallyformed on the first body 300 When the cantilevered part 30 c is formedand removed, a hole 301 h is formed on the first body 300. The paper-boxhandle structure 100 comprises plastic or other flexible materials.

The cantilevered part 30 c comprises a fixed end 33 securely connectedto the first body 300, a free end 31 formed with an engaging portion 34,and a middle portion 32 formed between the free end 31 and the fixed end33. With respect to Y direction of a coordinate system X-Y, the opening41 of the folding region 40 comprises a first width d1 and the engagingportion 34 of the free end 31 comprises a second width d2 greater thanthe first width d1.

In FIG. 4, when the folding region 40 folded along the folding line 50is attached to one side of the first body 300 of the handling region 30,the free end 31 of the cantilevered part 30 c sequentially passesthrough the hole 301 h of the first body 300 and the opening 41 of thefolding region 40, thus, the engaging portion 34 of the free end 31 ofthe cantilevered part 30 c is engaged to the opening 41 of the foldingregion 40 to form a handle 100′. When the paper-box handle structure 100is disposed on a plate b20 of a paper box B, the middle portion 32 ispulled through a hole (not shown in Figs.) of the plate b20 of a paperbox B.

Due to the size difference between the opening 41 of the folding region40 and the engaging portion 34 of the cantilevered part 30 c, the freeend 31 of the cantilevered part 30 c is limitedly engaged to the opening41 of the folding region 40 when the free end 31 of the cantileveredpart 30 c passes through the opening 41 of the folding region 40. Thus,paper box B is carried by holding the middle portion 32 of thecantilevered part 30 c.

Based on the described features, the paper-box handle structure 100 ofthe embodiment is directly formed by a single plate and capable of rapidassembly on a production line, thus, material costs are reduced, and theassembly process is simplified.

While the invention has been described by way of example and in terms ofthe preferred embodiments, it is to be understood that the invention isnot limited to the disclosed embodiments. To the contrary, it isintended to cover various modifications and similar arrangements (aswould be apparent to those skilled in the art). Therefore, the scope ofthe appended claims should be accorded the broadest interpretation so asto encompass all such modifications and similar arrangements.
